BATHiNG=TUB FOR BIPOLAR GALVANIC BATHS.

SPECIFICATION forming part of Letters Patent No. 710,933, dated October 7, 1902.

Application filed December 12,1901. Serial No. 85,673. (No model.)

$0 mil 1071,0777, it may concern:

Be it known that I, JosnF ZWIEBEL, proprietor of a sanitary establishment, a subject of the King of Bavaria, residing at Neu-Ulm, Bavaria, in the German Empire, have invented certain new and useful Improvements in and connected with a Bathing-Tub for a Dipolar Galvanic Bath, of which the following is a specification.

The present invention relates to a bathingtub for electric, and particularly for tan, baths which answers all hygienic requirements and allows of the electric current more or less to act upon different parts of the body.

The invention is illustrated in the accompanying drawings, in which similar letters denote similar parts, and in which Figure 1 is a horizontal section of the tub. Figs. 2 and 3 are details.

In the drawings, CL denotes the tub, which, as shown, is of ordinary shape and preferably made of oak wood in form of a cask, the end wall of the tub at the head being inclined to form a comfortable support for the back of the bather and inclosed by tin lined zinc strips. The same may, however, be made of other non-conductive material, as flagstone, the. Oak wood is preferable to the ordinarily-used pine wood or wild pine wood, because the latter becomes easily cracked by the heat and when wet, wood fungus or dry rot is formed.

The tub is provided on both sides with recesses 1), through which metal rods, preferably brass rods c, pass parallel to the longer sides of the tub. Carbon electrodes d, Figs. 1, 2, are attached to the metal rods 0, so as to be easily removable therefrom. Thus the electrodes are each provided at the upper end with a short bent metal piece or hook 6, so that they may be detachably suspended from the rods, the metal pieces or books being out of contact with the water and having no injurious effect upon the bather. The recesses 12 are laterally of such a length that the metal rods 0 and their electrodes can be readily moved toward or away from the body of the bather. The recesses I) can also be closed on the upper side by means of a cover f, having a turning-joint. The conducting-wires g for the electric current are attached to and held fast upon the ends of the rods 0 by means of r a nut It.

On both shorter sides or ends of the tub similar metal rods 0 are arranged, which, however, need not be movable, but pass through the wood of the tub-body to the conducting-wires g and are suitably fastened in place. In front of the metal rods 0 a frame or guard n may be secured to the wall of the tub by means of wood-screws to prevent the bather from touching the metal parts. The outlet of the tub may be closed up by means of a, stopper 7 of cork wood, which is attached to a leather belt 7t. By the employment of such material for the stopper and belt the bather is protected against injury when striking against these parts.

As seen, the metal parts of the present tub are out of contact with the water, so that the formation of injurious metal salts within the bath is obviated. The tub may be covered by a frame Z, Fig. 3, which may be attached to the tub in any suitable manner. This frame is preferably provided with an oil sailcloth on, so as to leave only the head of the bather free. Owing to this arrangement even persons sufiering with a cold may use the bath,because theirbody is always surrounded by hot vapors arising from within the bath and the patients enjoy a kind of a steam-bath. Since the present tub is provided with conducting-rods, not only at the opposite sides, but at the ends as well, the current may pass through the body of the patient from the head to the feet, as well as from one to the other side of it, and since the different electrodes are easily removable and adjustable certain parts only of the body may be treated with the electric current. For this purpose the electrodes located near the parts which are not to be treated must be removed. Yet the electrodes may as well be moved so together as to lie nearer to the parts of the body which are to be treated by the current. In the same manner the longitudinal rods, with their electrodes may be displaced, so as to lie nearer to the parts of the body through which the current is to be conducted. Since the rods, together with the electrodes,are easily adjustable, the patient can enter the bath-tub without having the electrodes in his Way.

What I claim, and desire to secure by Letters Patent of the United States, is

1. The combination with abath-tub of nonconducting material, of metal rods supported within the tub, electrodes carried by the rods, and suitable electric conductors, substantially as set forth.

2. The combination with a bath-tub of nonconducting material,of metal rods adj ustably supported within the tub at the sides thereof, electrodes carried by and adjustable on the rods, and electric conductors connected to the rods, substantially as set forth.

3. The combination with a bath-tub of nonconducting material,of metal rods adjustably supported at the sides of the tub, stationary rods at the ends of the tub, electrodes carried by said rods, and suitable electric conductors, substantially as described.

4. The combination with a bath-tub of nonconducting material, of metal rods within the tub at the sides and ends thereof, electrodes adjustable on the rods, a guard for one of said rods, and suitable electric conductors, substantially as set forth.

5. The combination with a bath-tub of nonconducting material, of metal rods supported within the tub, carbon electrodes provided with metal hooks adapted to engage the rods, and electric conductors, substantially as described.

6. The combination with a bath-tub of nonconducting material, for electric baths, particularly tan-baths, of metal rods secured against detachment, being easily removable and adjustable toward each other, said rods conducting the electric current and having easily-removable narrow electrodes provided on their upper parts only with metal hooks, these electrodes being adapted to be moved toward or from each other, and a frame easily removable to cover the bath-tub, for the purpose and substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of subscribing witnesses.

JOSEF ZWIEBEL.
